JB-Algebras and Analytic Loos Symmetric Cones
SOUTHEAST ASIAN BULLETIN OF MATHEMATICS(2022)
摘要
In earlier papers the author has developed the theory of Loos symmetric cones, which are Loos symmetric spaces on an open cone Omega in a Banach space, and developed the foundations of a geometric theory based on (modified) Loos axioms for such cones. Such cones present an abstract version of the cone of positive elements in a C-i-algebra. In this paper the close connection between Loos symmetric cones and a special class of Jordan algebras called JB-algebras is developed. Recent work of C.-H. Chu is applied to show that every Loos symmetric cone arises as the cone of positive invertible elements of a unital JB-algebra and conversely that this JB-algebra is unique and can be constructed on the Banach space containing the Loos symmetric cone.
